摘要:A method for producing 1,4-bis(dichloromethyl)tetrafluorobenzene is disclosed, which is achieved by reacting tetrafluoroterephthaldehyde, SOCl 2 and organic solvents. In the synthesis of 1,4-bis(dichloromethyl)-tetrafluorobenzene by adding formamides as catalyst, there are remarkable advantages which include shortening the reaction time; simplifying the synthesizing steps and raising the yield of the product.
